Before today’s game, MLB.com’s StatCast released some interesting notes on the Colorado Rockies and Arizona Diamondbacks before the Wild Card Game tonight.

MLB.com’s StatCast released some intriguing numbers about some of the players that will see some action in tonight’s Wild Card Game.

StatCast on Jon Gray

Jon Gray’s slider and curveball have collectively yielded a .242 slugging percentage over 186 at-bats, which is sixth best in baseball.

3. Max Scherzer: .239

4. Carlos Carrasco: .234

5. Dinelson Lamet: .239

6. Jon Gray: .242

Also, they have not been hard hit as just 81 balls have been put in play against Gray’s curve and slider this year. Just 13 reached Statcast’s 95-mph baseline for hard contact, giving him one of the lowest rates in the game by percentage.

Notes on Greg Holland

Greg Holland’s slider has been on of the best in baseball this season. By opponent batting average, StatCast notes this.
